  1. 1. Anaerobic cellulose degrading bacteria isolated from biogas plants

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Caroline Sjöberg; [2023]
    Nyckelord :anaerobic bacteria; biogas; cellulose; cellobiose; VFA; enzyme activity; TRFLP;

    Sammanfattning : Two cellulose degrading bacteria, named BCISO-4 and DC1-18-4, were isolated from samples retrieved from two large scale biogas-plants. In order to investigate and determine information regarding their growth preferences multiple tests were performed. LÄS MER

  3. 2. Cultivating oleaginous yeast on spent mushroom substrate and logging residues hydrolysate : an assessment of yeast growth on side product substrates from the food, agriculture, and forestry industry

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robin Lukic; [2023]
    Nyckelord :Lignocellulose; side products; oleaginous yeast; yeast oil; microtiter plate system; redox indicator; yeast growth; spent mushroom substrate hydrolysate; logging residues hydrolysate;

    Sammanfattning : There is an interest in finding alternatives to vegetable oils because of negative environmental impact. Many green sectors generate an abundant amount of side products that are inedible and consist in large of lignocellulose rich materials. LÄS MER

  4. 3. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  5. 4. Characterization of ulvan polysaccharide degrading enzymes from Wenyingzhuangia fucanilytica

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :Erik Apelqvist; [2022]
    Nyckelord :Enzyme; Enzymatic characterization; Recombinant protein producaiton; Protien purification; E. coli; W. fucanilytica; Transformation; Overexpression; Seaweed; Ulvan; Polysaccharides; biotechnology; Biology and Life Sciences;

    Sammanfattning : The aim of this thesis was to fully characterize the enzyme WFp-105, including bioinformatic analysis, structural modeling, full activity and stability characterization and product determination. As well as for the enzyme WFp-37; optimize protein production in regard to expression strains and cultivation temperature, analyzing the genomic context as well as performing an initial activity detection.

  7. 5. Ultrasound pre-treatment of wheat bran to improve arabinoxylan extraction

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Louise Lundquist; [2022]
    Nyckelord :Ultrasound; Arabinoxylan; wheat bran; alkaline extraction;

    Sammanfattning : With increasing amounts of food waste and diet related diseases, the need to utilize our by-products of food for its health benefits and to limit the food waste has never been more prevalent. Wheat bran is a by-product from the wheat flour industry and contains a lot of dietary fibres which has a beneficial effect on human health. LÄS MER
